Application filed April 20, 1918. Serial No. 229,757.

To all whom it may concern:

Be it known that I, YVIILJAM W. BURESCH, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Bottle Capping Machines, of which the following, is a specification.

This invention relates to improvements. in machines for applying sheet metal bottle caps to bottles, and more particularly intended for the purpose of re-c'apping'bottles with crimped caps which havebeen removed from bottles.

In the accompanying drawing, Figure 1 is aside elevation of a machine embodying my invention;

Fig. 2 isa top plan view of the same;

Fig. 3 is an end elevation of the machine, looking from right toleft in Fig. '1'- Fig. a is a section on the line H of Fig. 2, on an enlarged scale, the crimping jaws being shown in open position;

ig. 5 is a section on the line 5-5 of Fig. 1'; and,

Fig. 6 a detail view, similar to Fig. 1, showing the crimping jaws closed.

Referring to'the drawing, A indicates a table or bed suitably supported as by means of end frames or legs a. Upon the bed is arranged a saddle or .rest 1, for supporting the bottles, one of which is indicated at X, in dotted lines, Fig. 1. Secured to one end of the table or bed are two pairs of vertically arranged guide strips 23,'these .pairs being parallel with one another, and the strips of each pair being separated by a cam plateor bar 4. A rectangular frame B is slidable vertically in these guides, this frame, as shown in Figs. 3 ande, comprising parallel side bars 5, which are connected at their ends by crossbars 6 and 6?, which cross bars, as shown, ifit between the pairs of guide strips .23. The frame B is normally held in an upper position by springs 7 and 8, connected to the lower cross bar 6 and to a metal strip 9, which latter is secured to the table bed and extends around the vertically sliding frame B, as shown in Figs. 1, 2 and 8. The sliding frame B is movableina downward direction by means of a link 10, which is connected to :a rocker'arm 11,;on a rock shaft 12, journaled in the end frames of the machine, whichshaft'may be rocked, to move down the sliding frame B, by the depression of a treadle 13, secured to the rock stop for the capped end of crimped on.

shaft. Depending centrally from the up per cross bar 6 of the sliding frame is an arm or bar 14, having at its lower end a semi-circular head 15 upon which is removably secured a jaw 16, having a semiannular row of crimping teeth 16. The head v15 is adapted to slide between the bars 4, which serve as filling pieces between the guide bars 2-3. Below the jaw 16 are two jaws 17'and 18, each in theform of a quad rant and having crimping teeth 17 and 17*. These jaws are mounted upon heads 19 and 20, which are integral with arms 21 and 22, respectively, said arms being connected together at their lower ends by a pivot 23, which also connects the arms to a crosu piece 24, adapted to slide within the grooves formed by thetwo pairs of guide bars 2+3. A bow spring 25, connected with the'heads 19 and 20, tends constantly to force these heads apart. The heads 19 and 20 have at their upper ends outwardly projecting nodes 19 and 20 and the adjacent faces of the bars 4. are provided with notches 26, (see Figs. 4 and 5) into which these nodes extend when the heads are in the position shown in Fig. &. The lower edges of the notches are inclined downwardly and toward one another, as shown at 26*, forming cam surfaces which force the heads 19 and 20 toward one another when the latter are moveddownward, as shown in Fig. Normally these quadrants and the cross piece 24, to which the arms of the quadrants are connected, are held in the upper position shown in Fig. a, with the nodes extending into the notches 26 by a spring. 27,0011- nected to the pivot pin 23 and to a lug 28, projecting from a back piece 29, which is secured to the guide bars 2 and forms a the bottle when the bottle is in position to have the cap The notches 26 limit the up ward movement of the quadrants and connected parts.

The operation of the parts thus far describedis as follows: After the cap has been placed over the mouth of the bottle, the bottle is laid uponthe saddle 1 and pushed to the right in Fig. 1, until the bottle cap comes against the stop plate 29, when the flange on the cap will be between the teeth on the crimping jaw. The treadle 13 is then depressed and this in turn causes the frame B to-move downward, carrying with it the upper semi-circular jaw 16, which engages the flange of the bottle cap and forces the latter against the lower Th6 downward pressure of the upper jaw against. the bottle cap and bottle neck forces the two lower jaws downwardly, am: as they move downwardly they are also forced iinvardly by the cam surfaces 19, shown in Fig. :3, wherein the crimping jaws form a complete circle. "it will be evident that this action will cause the cap to be crimpcd in behind the lip on the bottle. YVllC-il the operator releases the treadlc 13, the springs T and 8 lift the frame l; and the crimping jaw 16 returns to its upper position, releasing the bottle and relieving tie pressure on the lower jaws, which a then moved upward by the spring 27 till; spread outwardly by the spring in order to insure the proper positioning of the bottles against the stop plate 29, l. provide a slide 30, which is movable toward and from the crimping jaws, in a suitable guide frame 31, mounted on the table or bed. This slide is provided with a vertically arranged disk 32, adapted to lit against the rear end of the bottle so that when the slide is moved to the right, in Fig. 1, it will press the bottle toward the stop plate 29. lhe pusher or positioning device, composed of this slide and dish, is normally held in the position shown in Figs. 1 and 2, by a spring 33,. and it is movable to the right, to position the bottle, by a bell crank B l, connected by a link 35, to the rocker arm 36 on the treadle shaft 12.

Nhen a bottle is placed upon this saddle and the treadle is depressed, the pusher is thereby moved forward and, engaging the bottle, presses its capped end against the stop plate 29. About the time the cap engages the stop plate, the crimping jaws engage the flange on the cap and crimp it, thus securing the cap to the bottle. The attachment for moving the bottle into position is not essential, but is desirable in order that each bottle may be correctly positioned automatically when the crimping jaws are brought together.

What 1 claim is:

1. in a machine for crimping flanged caps on to bottles, suitable guideways, a pair of arcuate crimping jaws slidably mounted therein and normally spaced apart, an independently movable arcuate crimping jaw adapted to force the bottle cap against said pair oi jaws and move the latter from normal positions, and means for forcing said pair of jaws toward one another when moved from normal positions.

2. In a machine for crimping flanged caps on to bottles, suitable guideways, a pair of pivotally connected arcuate crimping so obtained for slidably each, by tlommissioner mounted therein and normally spaced apart, an independently movable arcuate crimping jaw adapted to force the bottle cap against said. pair of jaws and move the latter from normal positions, and means for forcing said pair of jaws toward one another when moved. from normal positions.

3. in a machine "for crimping flanged caps on to bottles, opposed guideways, a pair of pivotally connected arcuate crimping jaws slidable in said guideways and yieldably supported in normal position, means normally tending to spread said jaws apart, said guideways having cam surfaces therein adapted to force the jaws toward one another when the latter are moved from normal positions, an independently movable arcnate crimping jaw adapted to torce the bottle cap into engagement with said pair oi and to move the latter from nor mal positions, and means for operating said independently movable jaw.

1. in a machine for crimping flanged caps on to bottles, opposed guideways having convergent cam surfaces therein, a pair of arcuate crimping jaws movable in said guidew ays in engagement with said cam surfaces, a spring for spreading said jaws, a spring for supporting said in normal positions, an independently movable jaw in said guidewavs. a spring normally holding said latter jaw away from said pair of jaws, and means for moving said. independently movable jaw toward said pair of jaws.

5. "in a machine for crimping flanged caps on to bottles, opposed guideways having convergent cam surfaces therein, a pair of arcuate crimping jaws movable in said guideways in engagement with said cam sur tacos, a spring for spreading said jaws, a spring for supporting said jaws in normal positions, a frame movable longitudinally of said guideways, means for reciprocating said frame, and crimping jaw on said frame adapted to press the pair of jaws against said cam surface-s when the frame is moved in one direction. I

6. in a machine for crimping flanged caps on bottles, suitable guideways, a pair 01 pivotally connected quadrant-shaped crimping jaws movable therein, means for spreading said jaws when moved in one direction and for pressing the jaws toward one another when moved in the opposite direction, semi-annular crimping jaw independently movcble in said guideways, and means for moving the latter jaw toward and from said pair of jaws.
